Microphone screen sE Electronics GuitaRF

The guitaRF helps get your amp sounding just the way you want.
The guitaRF acts as an RF (Reflexion Filter®), an isolator, a double mic stand, and fine-positioning hardware for both your favorite large-diaphragm condenser or ribbon mic AND a dynamic or small-capsule mic. All in one piece of gear, with the ability to perfectly phase-align the two capsules for maximum impact.
 
For years now, some of our biggest FOH engineer clients (running sound for Tom Petty & The Heartbreakers, Black Sabbath, Paramore, My Morning Jacket, and more) have known that putting a Reflexion Filter in front of their amp cabinets can help reduce stage bleed into their guitar mics. This is especially true with some of our favorite guitar mics like the VR1 and RNR1 ribbons, since they naturally have a figure-8 pattern that leaves them open to whatever else is happening on stage.

This doesn't just help the FOH mix either. Using an RF on a guitar cab or drums can make the multitrack of a live show significantly easier to mix.
Until now, our FOH engineer clients have had to devise their own custom-assembled solutions to help deal with this problem. Now, enter the guitaRF.

With the guitaRF, these custom rigs are now available as an off-the-shelf solution so anyone can get the guitar sounds they're looking for, with minimal stage bleed and coloration.

THE HARDWARE

The LDC/ribbon mounting hardware is adjustable across three axes - vertical, depth, and lateral - so you can find the perfect spot for any mic, whether in a shockmount or just on a clip.

This allows you to position both capsules perfectly in phase - or to spread them apart to capture the sounds of both the edge of the cone and the dust cap.

 
The entire filter + mic assembly can also be moved up and down to position it precisely over the perfect spot on the speaker cone - or, if needed, the filter can be removed from its base and mounted on any mic stand for complete flexibility.

THE FILTER

Acoustically, the guitaRF is very similar to our best-selling RF-X, with a four-layer acoustic filter design comprised of the vented outer composite panel, a layer of acoustic-grade wool, an air gap to help with low-frequency isolation, and an inner acoustic foam layer.

The guitaRF also has an integrated pass-through hole with a rubber-finned grip that securely holds just about any dynamic or small-capsule mic on the market. 

A double-cable clip is also provided that screws in to the back of the filter, so you don't need to worry about dangling mic cables that could accidentally tug your mics out of position.
